Windows 7/Vista/XP (32-bit and 64-bit) only

Note for Mac owners: The software does function properly under VMWare Fusion for the Mac when used with Intel Macs. With Fusion, Windows is run under a virtual machine and functions as if it was on a real Windows system. We do not recommend this with PowerPC Macs due to the substantial speed hit incurred. Intel Macs are able to execute natively most of the code on the CPU and the speed hit is relatively minor. The USB dongle is fully functional in this virtual environment.
